Collection location: near Snoqualmie Pass, King Co. and Kittatas Co., Washington, USA [Click for map]
This canopy is almost exclusively Western hemlock trees(in addition to a few thousand+yr old Spruce and Douglas fir) which we assumed would be host to a multitude of Oregon reishi. We could not have guessed more correctly! Piles of foot wide old reishi conks were found beneath this tree from multiple seasons prior. Truly amazing that nature’s vast and long lasting medicine chest is right before us in full view all the time.
It was the perfect Valentine’s day gift for us to find this canopy today! Can’t wait until next August to come to this location and see the fresh fruiting flush beginning to marshmallow out from all these spectacular hemlocks!
Old specimens from summer 2014: Still vibrant and varnished as one would encounter in the summer with G.oregonense- but this time of year they lack the bright white, marshmallowy pith that leads growth in warm humid summer months. In my opinion this is the time of year when the dark red varnish is most striking. By next summer these hollow, crispy conks will either fall off from the host substrate or be deep purple color and lose their varnished hue(unless they are rained on). Do not confuse with Fomitopsis pinicola. Fomitopsis is perennial(fruits from year to year, similar to Agarikon) and is heavy, corky and cannot be easily cut with a knife. Fresh and winterized Ganoderma alike can be sliced thin like bread slices from a loaf and are vibrant, shellacked red. Fomitopsis species are black and shiny, with a dense white flesh that is present year round. Also, Fomitopsis pinicola has only a red and sometimes orange band on leading edge(hence the common name “red belted” polypore).
All G. oregonense found today were parasitizing Western hemlock.
Most of these specimens were over a foot around in circumference.
Elevation: approx. 3000ft.
Temp: 58. Unusually warm for Feb.

Will do- and thanks for all your input and expertise on the Ganoderma. Love your page :).
The pore size can be used to distinguish, G.tsugae has smaller pores, about 3-4 per mm in my experience, compared to G.oregonense which has 2-3 per mm.
The spores in G.tsugae are also smaller being on average. 8.5x 5.6µm compared to G.oregonense which averages 10.5×6.7µm. I measure the spores from the internal spore wall since the external wall tends to break and become uneven.
I have not yet been sent a specimen from the PNW which matches G.tsugae in the east.I don’t think tree host is quite as important in Ganoderma as geographic location.
I am very interested in samples IDed as G.tsugae from the PNW.
Since it’s fruiting on Hemlock, how are you separating it from Ganoderma tsugae?
I am interested in collecting dried specimens for study. I am collecting oregonense to look for variation across the species.You can contact me via email at email@example.com Thank you!
It is a spectacular forest canopy for sure! I have never seen so many humongous Western hemlock or reishi for that matter :).
Next time you have time for a trip up to Washington we MUST plan something here. If I can get Mr. Winkler and maybe Mr. Miller from Alpental to get a crew together we could survey the snot outta this place! Truly a diverse forest ecosystem. I am adding an image of my wife Lara beneath one of the 800+yr old spruce we came across to show scale.
To answer MSchink’s question- we did not sample any of these because they were from last summer And were super waterlogged, unfortunately… Reishi should only be harvested for medicine when the fresh inner pith is still alive- latest in the season I have ever collected is October here in WA. If you are looking for a sample to be sent for vouchering or an herbarium specimen I will be more than willing to get you one soon and mail it out :)
Collect any of these specimens?
growing in a magnificent forest.
thanks for sharing. wish I was there! ;)
